Script label
<!--If you want to insert JavaScript into your HTML page, use the <script> tag. <script> and </script> will tell JavaScript where to start and end.
The lines of code between <script> and </script> contain JavaScript:
Just understand that the browser interprets and executes JavaScript between <script> and </script>.
Those old examples may use the type= "Text/javascript" in the <script> tag. There is no need to do so now. JavaScript is the default scripting language in all modern browsers and HTML5

<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>

<!---haha learned the call to the Java Script external file
Remember to refer to external files ...

To use an external file, set the. js file in the "src" attribute of the <script> label:
-->
<! DOCTYPE html>
<meta http-equiv= "Content-type" content= "text/html charset=utf-8"/>
</center>
<body>
<p id= "Demo" >a paragraph.</p>
<button type= "button" onclick= "MyFunction ()" > click here </button>
<button type= "button" onclick= "myfunction_1 ()" > Return </button>
<p><b> Note: </b>myfunction is saved in an external file named "Myscript.js". </p>
<script type= "Text/javascript" src= "Myscript.js" ></script>
<script type= "Text/javascript" src= "Myscript_1.js" ></script>
</body>

function MyFunction ()
{
document.getElementById ("Demo"). Innerhtml= "I love my famliy!!!";
